There's servos, then there are servos, what's the difference. Long story short, broke the tabs off Blue Bird made in Taiwan BMS-373MG metal gear tail servo and may not b able to attach it to my 450 in the standard fashion.

Out of the heli came a servo which was out of a styro plank originally, >94091. This servo was replaced when I paired up 2 JR DS285's with a third to make a matched set for the swash.

Today, I fiddle with the tail boom to make a small mod and in the process break the BB servo screw tabs off. This servo would have eaten it in a small crash, cheap plastic. The mounting part of the servo should be made of alu imo.

I had no choice but to mount the >94091 in its place. Plugged 450 in and waved heli tail back and forth. I never knew a servo could work so well, but what are the limitations. The >94091 came out of a plank, will it be quick enough to hold the tail in flight. It worked very nicely applying more tail blade pitch as the heli was gradually rotated in either direction.

Will it be ok to use the planker servo for the tail hh? I plan to add chinese weights to the tail rotor clamps to ease resistance to the servo/gyro.

If I could cut all the wires to the minimum length need to make every connection I would even go so far to solder everything directly rather than deal with (?)ohm resistance across pin connectors.

The 091 isn't as fast as typical tail servo but you will see the slop more on cyclic since it is not a BB servo. On T/R it will be OK.

ah ha, and the Blue Bird 373 wasn't a tail servo either. Glad for the replies Tmoore. After searching the net and coming across the "best tail servo" thread on rr https://rc.runryder.com/helicopter/t411621p1/ a comparison between a "tail servo" and a regular cyclic one was easier to understand.

I was forced to look at everything I had gotten with the used 450. Mismatched servos, broken AR6100 antenna, improperly mounted skids, a couple of loose frame screws, hot glue and cf rod to do what on the base plate ???

Adding Chinese weights to the tail clamps should improve the 091's performance marginally.
